【Bicycle helmet safety standard】US/Canada: CPSC, 16 CFR 1307,16 CFR 1203: safety standard for bicycle helmets.Europe: BS EN 1078:2012+A1:2012. Recommended age range: 10 years and above. Recommended head circumference: 57~62cm. [High impact resistance & lightweight] Shinmax bicycle helmets are designed for adults, but the size is adjustable, so children can also use them within the applicable range. The exterior is covered with a sturdy PC material, and the interior is made of highly impact-absorbing EPS material to protect the rider's head. While ensuring safety, the lightweight structure makes it comfortable to wear. [Bicycle helmet with taillight] Equipped with a taillight for safety at night, including 3 modes (flashing, fast flashing, constant light), it is more visible on dark roads, improves visibility, and increases safety.

The dial adjuster on the back of the head can be tightened by turning the dial, providing a snug fit that wraps around the back of the head and ensuring safety. [Excellent breathability] A casual shield-style bicycle helmet that looks cool. The aerodynamically designed ventilation holes allow air to pass through easily. Scientific analysis based on wind tunnel experiments has significantly improved the breathability inside the helmet at low speeds, effectively reducing air resistance and efficiently expelling hot air inside the helmet, making you feel more comfortable.
